Sungine · Human Body Sensing Sensor · DIP-16
GC7780AD from Sungine, in a DIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | input | Repeat-trigger control: A=1 allows retriggering, A=0 gives non-retriggerable operation (input high min 3.5V, low max 1.5V at VDD=5V). |
| 2 | VO | output | Control signal output that goes high on a valid trigger (rising edge of VS) and stays low outside delay time TX and when there is no VS rising edge. |
| 3 | RR1 | passive | Output delay time TX adjustment terminal with R1, where TX ≈ 49152·R1·C1. |
| 4 | RC1 | passive | Output delay time TX adjustment terminal with C1, where TX ≈ 49152·R1·C1. |
| 5 | RC2 | passive | Trigger lockout time Ti adjustment terminal with C2, where Ti ≈ 24·R2·C2. |
| 6 | RR2 | passive | Trigger lockout time Ti adjustment terminal with R2, where Ti ≈ 24·R2·C2. |
| 7 | VSS | power_in | Negative supply terminal, normally connected to 0V. |
| 8 | VRF/RESET | input | Reference voltage and reset input, normally tied to VDD; taking it to 0 resets the timers. |
| 9 | VC | input | Trigger inhibit input: triggering is inhibited when VCVR, with VR≈0.2VDD. |
| 10 | IB | passive | Op-amp bias current setting terminal, connected to VSS through RB of about 1MΩ. |
| 11 | VDD | power_in | Positive supply terminal, range 3 to 12V. |
| 12 | 2OUT | output | Output of the second-stage operational amplifier. |
| 13 | 2IN- | input | Inverting input of the second-stage operational amplifier. |
| 14 | 1IN+ | input | Non-inverting input of the first-stage operational amplifier. |
| 15 | 1IN- | input | Inverting input of the first-stage operational amplifier. |
| 16 | 1OUT | output | Output of the first-stage operational amplifier. |
